[Sandesha2][New feature] RMFaultCallback

[Chamikara Jayalath <ch...@gmail.com>]

Hi All,

It seemed that there is no way to inform the clients about the faults that
come for RM control messages such as CreateSequenceRequest. But
CreateSequenceRequest is the first message that is sent by a RM client and a
fault comming for that may be important.

For example when both RM and Security are present the fault that come due to
the CreateSequence may be something like a authentication failure and its
great if we can give the client the ability to programatically handle such
cases.

I added a feature to support this. Here clients can set a property in the
'options' object giving an implementation of the RMFaultCallback class. In
case of a fault the 'onError' method of this callback will be called giving
the axisFault object as a parameter.
